OIL GELLAR.

Application ined May 29, 192e. serial No. i12/515.`

This invention relates to the oil cellars used on locomotives, engine trucks, and on trailer journals or on any journal or bear` ing on the inner side of the wheels where it is not possible to use a onepiece oil boX and support for bearing wedge and brass. Journal boxes of this description now in use have a plain cellar under the journal held up to the jQurnal by cellar bolts which extend under the cellar and through the legs of the box and hence the packing in the cellar only gets its oil through a hole in the top of the box and brass. lVhen the packing on top of these boxes Igets hard or filled with dirt or the oil hole gets stopped vwith dirt or Babbitting metal or the packing gets saturated with water, the packing in the cellar gets dry and hard, and thus the bearing runs hot. In many cases the journal cuts and causes expense and delays.

The general object of the present invention is to provide an oil cellar so constructed that the oil will be delivered to the packing in the cellar on each side of the journal, thus insuring perfect lubrication whether or not the packing' gets any oil from the top of the drive. engine truck, or trailer boxes.

Another object is to provide means for preventing the packing from rolling up between the bearing or journal and the cellar and another object is to allow a greater amount of packing to be used at this point so as to receive the drip from the oil reservoir of the cellar.

A. further object is to provide a construction of this character in which the cellar is formed with a cavity or reservoir on each side wall, this cavity being so formed as to insure a uniform flow of oil and a uniform deliver)Y of oil to the packing at uniformly spaced points.

il still further object is to provide a cellar having oil pockets or reservoirs which will lubricate the packing on both sides of the journal or bearing, thus insuring thatk the lubricant shall be taken up to the bearing ou one side and down into the packing on the opposite side regardless of which way the journal or bearing is turning. 1

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings wherein Figure 1 is an end elevation of a cellar constructed in accordance with my invention;

Fig. 2 is a longitudinal sectional view thereof; Y i

Fig. 3 is a section on the line 3 3 of Figure 4;

Fig. 4 is a section on the line 4 4 of Figure 3; i f 1 Figures 5, 6, 7 and 8 are sections on lines 5, 6 6, 7 7. and 8 8 of Figure 2.

Referring to these drawings 10 designates t-he cellar generally which is formed with the end walls 11, the side walls 12, and the bottom wall 13. The end walls l1 are, of

course, cut away circularly at their ends as at 14, and a shoulder is formed on the inside face of each side wall, -this shoulder extending the entire length of the side wall.

Formed in these side walls above the shoulders 15 arethe oil pockets V16, these pockets being disposed each at one end of .a side wall. Leading from the upper end -of each pocket is a longitudinally extending duct 17, the bottom of which duct inclines downward and away from the pocket 16. The bottom of each pocket is formed to provide a plurality of grooves as, for instance7 four grooves and formed at intervals along each wall of the cellar are the discharge ducts or feed tips 18` There are as many of these feed tips as there are grooves and t-hese tips are arranged on an inclined plane extending longitudinally of the cellar so that the feed tips are successively lower away from the pocket 16. Thus. the first fed tip intersects the first groove of the series, the second feed tip extends back to the second groove, the third back to the third lgroove and the fourth feed tip eX- tends back to the outer wall of the duct 17, as illustrated in the sections. (lil drops from the pockets or tips e, '/f, g and 7L onto the packing which is held by the Lcellar under the journal or bearing. Thus, oil is applied directly onto the packing at all times, insuring perfect lubrication. The oil pocket 16 insures a uniform flow of oil into each groove a, 7n, c or (Z when the oil reaches a level in the pocket which will cause an overflow into these grooves. `The grooves a. 2'), c, and Zrun downward at an `inclination from the outside to the inside end of the cellar so that gravity will insure the oil running in a uniform quantity from the oil pocket 16 to the ports or tips e, j", g and feeding, therefore, uniformly into the packing in the cellar.

The shoulder 15 on each side wall ofthe cellar acts yto prevent the packing from being rolled up between the journal or bearing and the cellar and also allows a gr iter amount of packing at this point for the oil 'trom ,tue ports to drop onto. The packing may be wool waste or cotton vaste, straight wool, sponge or any other fibrous material. Oil is discharged into the pocket 13G by means el? an oil pipe or oil cup that screws into the Gellar at 19.. It will be seen that this construction not only secure the advantages which have ,been referred to Lieietoare out that as all journals throw oli' .more or l c heat caused by friction, the Vjournal will com-- municate the heat to the packing which in turn communicates it :to the cellarior the full length of 'the eil ca "y or duct, thus insuring Aa free feed et oil in cold wef The Aobject of the grooves formerL in the ogor or bottom et `the, duct l? is to ses uniform amount of oil for each of ti Whenthe pocket is iilled to overl'lewi otherwise Iit the door et grooves, the lowest'port or tip would get greatest amount et oil and the Aport i f highest position would cease to get the level of the oil is below it. The ports le are formed each with an over-han g lip "which is disposed at an angle and projects slightly from lthe wall `el the cellar next to the journal. This is so that the eil may dro immediately. ofi the orerhangi tip vor lip onto the lpacking `instead oi running bach under the lip which would be the case if these lips were horizontal insteiul oi down wardlly and laterally inclined.

v@une of :the important advantages ot my invent-ion is that the oil is furnished te the packing continuously and thus the packing is saturated at .all times with oil. Thus, `vvd-hen properly packed the cellar and packing should function indelinitely without .it being necessary to repacl. lilith the old style sellar now infuse it is necessL 'y to paci; the cellar each tri-p and sometimes between terminals.

l. An'foil cellar tor journal boxes hav side Wallsfeach side 'wall being ormed win an oil pocket at Vitsv forward end and a duct extending :rearward `from the oclet and havin-g its Jbottom sloping .f illy and downwardly, each side wail of the cellar be ing formed `with ports communicating w :the interior of :the `duct adjacent its bottom, and the :ports being disposed at spaced internals. y

2. An oil bell-ar for journal boxes having Side Wal-ls, each side fwall being formed at n le Y when its forwardend with an oil pocket .and with a longitudinally extendiiie` duct extending from the top of the oil pocket, the bottom of each oil duct having a downward inclination toward the rear of the pocket and the bottom of each oil duct being Aformed to provide a plurality ot channels, each y side wall ha ing downwardly and laterally extending port-s communicating with said grooves.

3. iin loil ycellar tor journal boxes having side walls, each side wall having at its iorward end au oil pocket and having Ya longitudinally extending duct extending from 'the top et the-oil pocket, each duct at its bottom being inclined downward and rearward fand 'formed with la plurality of grooves7 and each side wall vhaving ports extending upward and laterally and communicatinrT 'with 'the duct, the longitudinal grooves successively terminating at successive ports.
